SUMMARY OF DISCLOSURE

[0008] Aspects of the teachings of the present disclosure may be mentioned as a surgical collection set for filtering material from liquid obtained during surgery; the surgical collection set has a container. The container has: 1. an open end that can be reversibly sealed with a container lid; 2. an inlet adapted for connection to a suction line; 3. an outlet adapted for connection to a suction line; 4. a set of guiding features for positioning an upper portion of a collection basket within the container such that an upper portion of the collection basket does not impede a flow of material into the container through the inlet; 5. a bottom surface with a grooved path template on the bottom surface, the grooved path template being connected to the outlet;

[0009] The surgical collection set also has a collection basket with side walls and a bottom connected to an upper portion of the collection basket, so that the upper portion of the collection basket can be used to position the collection basket inside the container.

[0010] The surgical collection set also has a plunger set. The plunger assembly has a canister cap that can be reversibly connected to the open end of the canister; the container lid has an orifice that allows a plunger rod having a distal end to move relative to the container lid, so that a distal end of a plunger can be used to compress the collected material into the collection basket for help to remove fluids from the collected material.

[0011] The plunger assembly also has a plunger with a distal end for compressing the collected material and a plunger rod for passing through the hole in the container lid, so that a proximal end of the plunger can be moved by a user.

[0012] The surgical collection set is adapted to allow suction applied to the outlet of the container to aspirate liquid and non-liquid material through a tube connected to the inlet of the container; liquid and non-liquid material passes into the collection basket, with a good portion of the liquid exiting the collection basket through at least a portion of the collection basket to enter the grooved pathway template on the bottom surface and then exit through the outlet leaving a filtered portion of the non-liquid material in the collection basket.

[0013] For certain uses, the surgical collection set may have a simple container lid without an integrated plunger.

[0014] The teaching aspects of the present disclosure can be summarized as a method of gathering material collected from a surgical procedure and compressing the collected material to remove fluids. The method includes inserting a first collection basket into a collection container. The collection container has an inlet and an outlet. The outlet of the collection vessel is in fluid communication with a grooved template on one side of the basket of a lower portion of the collection vessel. Applying suction to the outlet will draw the material through the inlet tube connected to the inlet, the material passes through the inlet, whereby at least part of the fluid in the material passes through the first collection basket into the slotted jig and then at the exit to leave the filtered material in the first collection basket. The step of inserting the first collection basket into the collection container guided by an interaction between the collection container and the first collection basket prevents placing an assembly of at least one basket handle in a position which obstructs entry.

[0015] The method includes placing a plunger assembly in the collection container; connecting the inlet piping to the inlet; and connecting the outlet piping to the outlet. The order of these three actions is not crucial to the method.

[0016] The method includes applying suction to the outlet tubing connected to the outlet, so that whenever a non-container end of the inlet tubing is placed in a surgical site, fluids and small materials are sucked through the outlet tubing. entrance through the entrance and into the first collection basket.

[0017] The method includes removing a non-container end of the inlet tubing from the surgical site and using the plunger assembly to drive a distal end of a plunger down to compress the collected materials in the first basket collection.

[0018] Includes removing the plunger assembly from the collection vessel while the inlet piping is still connected to the inlet and while the outlet piping is still connected to the outlet, and removal of the first collection basket with compressed material from the collection container.

[0019] Includes repeating the process with a second collection basket which may be the first collection basket after material is removed from the first collection basket.

DETAILED DESCRIPTION

[0061] FIG. 1 shows an exploded front view of a surgical collection set 100. As seen in FIG. 1 the container 120 with the inlet 124 and outlet 128. The inlet 124 and outlet 128 may be shaped to hold the tubing as a trimmed profile. Container 120 has a set of male threads 132 for engaging a corresponding set of female threads 216 (not shown here) inside cap 204.

[0062] A basket ring 158 is used to position the basket 150 within the container 120 to allow the basket to collect filtered material from a stream of material aspirated from the surgical site. Basket 150 may be constructed so that a basket sidewall 154 is connected to a basket bottom 156.

[0063] Suction applied to the outlet 128 of the container 120 through the side suction tubing (not shown) draws material from the surgical site into the side surgical tubing (not shown), into the inlet 124 of the container 120 and into basket 150. Suction pressure removes much of the liquid content of the material delivered to basket 150, as basket 150 serves as a filter to separate non-liquids from liquids removed from the surgical site.

[0064] A plunger assembly 200 has a plunger rod 220 with a broad distal end 224 that can be moved to compress the contents of the basket 150 to remove additional fluid from the collected material. Plunger rod 220 has a proximal end 228 that fits through a hole 232 (not visible here). Bushing 212 and O-ring 208 help maintain a vacuum seal around piston rod 220. Bushing 212 is press fit into hole 232 to secure O-ring 208 so that it fits tightly around piston rod 220 and into the bore to provide a proper vacuum seal. The vacuum seal need not be perfect, but it should be sufficient such that the suction applied to outlet 128 to supply suction to inlet 124 is sufficient for use in aspirating material from the surgical site. If the opening in the surgical site is covered by something that cannot be sucked into the opening, then the suction can draw some air through the seal around the plunger rod 220, however small amounts of internal leakage are not a problem.

[0065] The proximal end 228 of the plunger rod 220 fits through the inside of the spring 260 and into a hole in the handle of the plunger rod 240. The connection between the proximal end 228 of the plunger rod 220 and the hole in the handle of the piston rod 240 can be realized in several ways. The connection can be a threaded connection and therefore reversible. The connection may be a non-reversible connection made by any of a number of techniques known to those skilled in the art, including a press-fit. Glue can be used instead of a press fit if a tight connection is desired.

[0066] The spring 260 holds the plunger rod 220 in an elevated position with the distal end 224 of the plunger rod 220 above the flow of material entering the vessel 120 through the inlet 124. The handle of the plunger rod 240 can be pushed down against spring force to push the distal end 224 of the plunger rod 220 down to compress the collected material in the basket 150 to remove more fluid.

[0067] FIG. 2 provides a front view of the surgical collection set 100. FIG. 3 shows a cross section of the view of FIG. 2 taken through the intermediate lines of input 124 and output 128.

[0068] Can be seen in FIG. 2 and in FIG. 3 previously mentioned elements: piston rod handle 240, piston rod 220, spring 260, bushing 212, cover 204, inlet 124, container 120 and outlet 128.

[0069] Additional elements that can be seen in FIG. 3 and which cannot be seen in FIG. 2 include: O-ring 208 resting on shoulder 236 in bore 232, proximal end 228 of plunger rod 220, distal end 224 of plunger rod 220, basket ring 158, basket 150, female threads 216 in cap 204, and male threads 132 in container 120.

[0070] Note that FIG. 3 shows a view of the seal around piston rod 220 as bushing 212 engages O-ring 208 between bushing 212 and shoulder 236 inside bore 232 of cap 204.

[0071] A cautious observer will verify that the model shows the O-ring 208 in the shape it assumes before engagement with the piston rod 220 without a cap. The O-ring is compressed between the piston rod 220 and the cap 204. However, the bushing 212 is not designed to compress the O-ring 208.

[0072] FIG. 4 shows the piston rod 220 moved down so that the distal end 224 of the piston rod 220 is just above the basket bottom 156. The force applied to the loop of the piston rod 240 has compressed the spring 260. seen in this figure the lid 204 and the basket ring 158. To show the relationship between the distal end 224 of the piston rod 220 and the basket bottom 156, the container 120 and the side walls of the basket 150 have been hidden.

[0073] Upon release of the plunger rod handle 240, the distal end 224 of the plunger rod 220 will move upward relative to the basket 150 as the spring force is sufficient to return the plunger rod handle 240 to the top position. It is possible that, during compression of the collected material, some collected material may fill any voids between the outer perimeter of the distal end 224 of the plunger rod 220 and the inner perimeter of the basket 150. To minimize any tendency for the basket 150 to rise out of position, basket ring 158 has a pair of loops 162 (one loop being visible in FIG. 3). The upper edge 160 of the handle 162 is positioned very close to the inner face 206 of the cap 204, so that the distal end 224 of the plunger rod 220 continues to move upward after the upper edge 160 of the handle 162 reaches the inner face. 206 of cap 204 so that basket 150 is offset from distal end 224 of piston rod 220.

[0074] Placement of Input and Output in Container.

[0075] Note that by having both the inlet 124 and the outlet 128 located in the container 120 and not divided between the container 120 and the cap 204, rotation of the plunger and cap assembly 200 to remove the plunger and cap assembly 200 and exposing the interior of the vessel 120 can be accomplished without disconnecting the side vacuum tubing connecting the outlet 128 to the vacuum source and without disconnecting the surgical side tubing connected to the inlet 124. Thus, neither the connection of the tubing to the inlet 124 or the outlet 128 needs to be a more expensive quick-disconnect connection, as is the case with a bayonet connection.

[0076] By allowing the quick removal of the plunger and cap assembly 200 from the surgical collection assembly 100 to expose the basket 150, it allows the collected material to be removed and a new basket 150 to be inserted. Once connections to inlet 124 and outlet 128 are in place, the collection process can be quickly resumed after plunger and cap assembly 200 is re-fitted to canister 120.

[0077] A second advantage of having the port 124 in the canister 120 rather than the lid 204 is that this placement helps to prevent material arriving through the port from rising up on the upper side of the broad distal end 224 of the piston rod 220 This avoids wasting material that could have collected in the basket 150 and reduces the chances of the material interfering with the operation of the piston rod 220.

[0078] When using the plunger rod 220 to press the collected material, an operator may wish to lift the surgical end of the surgical side tubing out of the surgical site so that only air enters through the inlet 124. The suction source can be maintained during this process to help remove fluids that are pressed out of the collected material.

[0079] FIG. 5 is a perspective top front view of container 120. For purposes of illustration, a basket ring 158 can be seen in FIG. 5, but the basket ring 158 does not have a basket sidewall 154 or a basket bottom 156. FIG. 6 is the same view as in FIG. 5, however the basket ring 158 is removed so that the portions of the container 120 that support and position the basket ring 158 can be seen.

[0080] The basket ring 158 can be described as a pair of loops 162. Between the loops 162 are portions of the basket ring 158 which may be referred to as inter-loop segments 166. The inter-loop segments 166 can be distinguished from the intra-loop segments 170 which may be thinner than the interstrap segments 166.

[0081] The difference between the intra-loop segments 170 and the inter-loop segments 166 allows the basket ring 158 to be oriented within the container 120 to avoid blocking the inlet 124. The container 120 orients the basket ring 158 through the location of long ribs 136 and short ribs 140. The inter-loop segments 166 can rest on the shoulders of the short rib 144, but are too wide to line up with the long ribs 136. In contrast, the narrower intra-loop segments 170 can fit within of the perimeter formed by the upper portions 152 of the long ribs 136 and rest on the shoulders of the long rib 148.

[0082] Grooved Template.

[0083] As seen in FIG. 6, the container 120 has a bottom surface 190 that supports the bottom surface of the basket 150, even when the piston rod 220 is compressing material into the basket 150. A grooved template 194 disperses through the outlet mouth 198 so that active suction at outlet 128 applies suction pressure across slotted jig 194 to draw liquid from basket 150 and draw liquid into outlet mouth 198 and out through outlet 128. The jig used as slotted jig 194 need not be identical to the template shown here. Several different templates are possible. While symmetry on either side of a midline between input 124 and output 128 may be a natural choice, it is not required. The width and depth of the slotted template need not be uniform. A template that allows suction to reach a distal end of the template even if a small obstruction is lodged in a portion of the template has advantages over a template that lacks the cross-links that allow for alternate drainage pathways.

[0084] FIG. 7 shows a cross section of the container 120 taken again through the inlet 124 and the outlet 128. The cross section was rotated to move the lid 204 towards the viewer to allow the bottom surface 190, the slotted template 194 and the outlet mouth to 198 are visible in relation to the basket 150 and in particular the basket bottom 156. Note that the combination of the basket ring 158, the long ribs 136 and the short ribs 140 prevents flow from inlet 124 to outlet 128 passing in around the perimeter of the basket 150. Having the distal ends of the grooved template 194 terminate beyond the outer edges of the basket 150 allows for suction below the basket ring 158 to aspirate fluids from the side walls of the basket 154 in addition to aspirating fluids from the bottom of basket 156.

[0085] Basket Formation.

[0086] Various techniques can be used to produce a basket and basket ring assembly to hold the teachings of the present disclosure. As noted above, the basket can be made from a side wall joined to a bottom. The connection of the side wall with the bottom can be carried out by means of sewing. Alternatively, the connection of the sidewall to the bottom can be accomplished by placing a flexible ring on the perimeter of the bottom of the basket that connects both the sidewall and the bottom to the flexible ring. The connection may be through stitching, overmolding, heat sealing, or some other connection process that is suitable for use in collecting bone material that will be used in a surgical procedure. The connection to the basket ring can be heat sealed, soldered or adhesive connected. The bottom can be in the same plane as the lower edge of the side walls.

[0087] The presence of a flexible basket 150 allows the basket bottom 156 to be moved relative to the basket ring 158, so that the basket 150 is inverted so that the inner surfaces of the basket 150, during collection, become the outer surfaces of the basket 150 during the distribution of the collected material.

[0088] The basket material will be chosen by the designer as part of the total design, however a basket made of material that has an open area in the range of 47% with a mesh opening in the range of 200 micrometers can be used with certain baskets and applications . For context, 200 micrometers (also known as microns) represents the type of filtration that can be used to remove fine sand from a liquid.

[0089] Those skilled in the art will recognize that the disclosed surgical collection assembly 100 provides a basket with extensive filter surface area that allows continuous filtration throughout the collection process. The large surface area of the basket and other features of the disclosed surgical collection assembly 100 make the assembly resilient to the presence of material that could obstruct and impair another collection system.

[0090] Basket mobility is also important to allow the collected material to be transferred to the prep table, while allowing a lid to be replaced and regular suction to be maintained.

ALTERNATIVES AND VARIATIONS.

[0091] Input and output alignment.

[0092] The container 120 was shown with the inlet 124 displaced 180 degrees in relation to the outlet 128. It is believed that this displacement is useful, as it allows the captured product to fill the entire basket, since the flow is opposite to the diameter from the basket. If there are doors on the same side, the product can be accumulated on one side of the basket. By having the inlet 124 disposed above the basket and the outlet that sucks material from the bottom of the basket, the surgical collection assembly 100 is not based on gravity, since the suction force is sufficient to promote proper operation even in the in which case the container 120 is tipped over so that it is horizontal rather than vertical.

[0093] While there are advantages to having the inlet 124 offset 180 degrees relative to the outlet 128, there would be similar advantages with an offset relatively less than 180 degrees. Even a 90 degree offset would provide substantial advantages. Those skilled in the art will recognize that a surgical collection assembly 100 with an inlet 124 located directly above the outlet 128 would be a viable collection device even if that collection device does not have the suggested offset of 180 degrees.

[0094] The presence of the outlet 128 located near the bottom of the container 120 increases the ability of the collection device to be free of fluids compared to using the same suction source with an outlet placed near the top of the container.

[0095] Sample Collection Lid.

[0096] The container 120 and the basket 150 with the basket ring 158 can be used with an alternative lid 304 which does not have a hole for use with a plunger rod, but which is a solid lid. Such an alternative lid 304 may be used when the container 120 and basket 150 are employed to filter material aspirated by suction from a surgical site. This material could be bone that is prepared and reused, but more likely it will be material to be collected and sent for analysis.

[0097] FIG. 8 and FIG. 9 show a top and bottom perspective view of the alternative lid 304, including female threads 216 that engage mating male threads 132 of container 120.

[0098] Alternative Way to Avoid Entrance Blocking.

[0100] A method for orienting the basket ring to avoid interference with the ingress of suction material passing from the inlet to the interior of the basket has been disclosed above. The basket ring was oriented using an interaction between the basket ring 158 and the short rib shoulders 144 and the long rib shoulders 148.

[0101] An alternative way of orienting a basket ring 358 within the container 320 is disclosed. FIG. 10 provides a view of container 320 set transparent to allow a view of basket ring 358. Basket 150 is shown with only basket bottom 156 visible to avoid obstructing views of ribs 340. Basket ring 358 rests on a set of rib shoulders 344. The rib shoulders 344 on top of the set of ribs 340 define the height of the basket ring 358. A set of one or more guide tabs 380 define the orientation of the basket ring 358, such that the one or more lugs 362 are in defined positions relative to the set of ribs 340. As shown in FIG. 10, there are a pair of lugs 362 and these can be placed in a variety of positions including the presence of a lug 362 placed between the ribs 340 on either side of the inlet 124. The lug opening 364 is sized so that the flow of material from of container 320 from inlet 124 passes through loop opening 364 and loop 362 does not serve as an impediment.

[0102] Those skilled in the art will recognize that additional short ribs can be placed on the sidewall of the container 320 to avoid choosing to place the handle 362 close to the inlet, so that the handle opening 364 need not be sized to accommodate flow through handle opening 364.

[0103] While placing guide tabs 380 below handles 362 is one approach, guide tabs 380 could be placed in any other location. There does not need to be a one-to-one correspondence between the number of guide tabs and the number of handles.

[0104] FIG. 11 and FIG. 12 show the container 320 as a solid object. The basket is concealed to allow the ribs 340 and rib shoulders 344 to be visible. The difference between FIG. 11 and FIG. 12 is that the basket ring 358 is hidden in FIG. 12.

[0105] The container 320 and the basket 150 can be used with the plunger and lid assembly 200 if the material collected in the basket 150 needs to be compressed while in the container 320 or can be used with an alternative lid 304 if there is no intention of use a plunger to compress the collected material into the container 320.

[0106] The basket and rib concept introduced in FIG. 10, in FIG. 11 and in FIG. 12 can be used with container 420 and basket 454. One set of drawings shows these components without the clutter of marker lines and element numbers. A set of drawings without marker lines and element numbers shows a plunger and lid assembly 480 that can be used with container 420 and basket 454.

[0131] Kits.

[0132] The surgical collection set 100 with the container 120 and the plunger and cover set 200 can be supplied in a kit with a piece of suction tubing attached to the inlet port. The provision of suction piping ensures the use of a clean suction piping between the collection location and the inlet of vessel 120, so that the collected material is free of other debris that may have been generated and removed by other suction piping. . This can be important when the collected material, eg bone, is used for a specific purpose. Providing tubing with vessel 120 ensures that adequate flexible tubing is provided to ensure easier manipulation of the suction tubing end. Finally, providing the vessel 120 with tubing affixed to the inlet eliminates a source of error when configuring the surgical collection set.

[0133] The kit can contain two or more baskets. The kit may include an alternate cap 304 in addition to a plunger and cap assembly 200.

[0134] Non-circular container.

[0135] Note that although the examples provided in the present disclosure have a container with a circular cross section, those skilled in the art will recognize that a container with another cross section could be used. For example, the cross section could be oval or oval. Alternate cross sections may be used as long as the design has a properly functioning fit between the plunger assembly (or sample collection cap) and vessel. More likely this would be something other than a threaded fitting with the container. The basket assembly would need to be properly sized, but would not need to be the exact cross-sectional shape of the container.

[0136] Alternative Baskets.

[0137] While the use of baskets with liquid permeable bottoms and liquid permeable sides has been taught, those skilled in the art will recognize that for certain applications the bottom may be liquid permeable while the sidewalls are not. This may be suitable when the collection basket has a very large bottom surface or when the collection process is not intended to collect such an amount of filtered material that the filtered material sinks. This basket may look more like a relatively flat container than an elongated cylinder.

[0138] Alternatively, a basket may have a bottom that is not liquid permeable and rely on fluids being sucked out by the liquid permeable side walls. In this type of basket, the bottom of the basket can be made small so that the layers of collected materials accumulate, the materials are partially dried by the removal of fluids through the adjacent side walls. This type of basket may look more like an elongated cylinder than a relatively flat container.

[0139] Those skilled in the art will recognize that some of the alternative implementations defined above are not mutually universally exclusive and that, in some cases, additional implementations may be created that employ aspects of two or more of the variations described above. Likewise, the present disclosure is not limited to specific examples or particular embodiments provided to further understanding of the various teachings of the present disclosure. Furthermore, the scope of the following claims encompasses the range of variations, modifications and substitutes for the components described in the present invention, as would be known to those skilled in the art.
